Garmin GT34UHD-TH Ultra High-Definition Sonar System Thru-hull Transducer

Add stunningly clear Ultra High-Definition ClearVü and Ultra High-Definition SideVü scanning sonar images to your compatible chartplotter via the GCV™ 20 sonar module. It includes 3 arrays, including a downward-facing element element — with frequencies ranging from 0.8 MHz (800 kHz) to 1.2 MHz (1,200 kHz) — and it’s recommended for hulls with up to a 5-degree deadrise angle.

This mode provides brilliant image clarity of structure and fish below your boat at greater depths than other high-frequency scanning sonars by putting more power on targets via a downward-facing element.

This mode delivers stunningly clear images of structure and fish off to the sides of your boat. This makes it easy to scout a fishing area quickly, because you can see everything the first time with such amazing clarity.
